T-Mobile USA has been one of the first carriers to widely deploy IPv6, seeking to overcome the lack of IPv4 addresses and to lay the foundation for their network for the Internet of Everything. However, one of the headaches they’ve faced is that some applications which work fine over IPv4 don’t play nicely with IPv6. That’s a real challenge for service providers, impacting their ability to migrate completely away from IPv4 and complicating their network operations.

We’ve been actively promoting the adoption of IPv6 at various venues -- back in January at Cisco Live London, and a few weeks ago at the V6 World Congress, which focused on the adoption of IPv6 in mobile networks.

Our next big venue is Cisco Live in Orlando, Florida June 23-27, 2013 and I want to take the opportunity to reflect on how IPv6 is becoming an increasingly important component of the event agenda, infrastructure and look forward to some of our future ideas for Orlando.

I have personally participated in Cisco Live for over 15 years as a speaker but this was my first time as a member of the IPv6 Team. For those of you who do now know I am the Product Manager for IPv6 in Cisco’s Core Technology team that we call Network Operating Systems Technology Group.

My observations on what I saw and heard in London were as follows: Read More »

A few months back we announced how Hrvatski Telekom, Croatia’s largest telecommunications company, is using a Cisco’s end-to-end solution for its advanced TeraStream cloud-enabled Internet Protocol (IP) architecture. Operated by Deutsche Telekom subsidiary Hrvatski Telekom (T-HT), it’s initially providing broadband services to residential users in the Zagreb area of Croatia.

Segment routing (SR) is a concept that’s been working its way through the IETF standards process but is finally becoming ready for real world deployment. It’s a network technology that provides enhanced packet forwarding behavior while minimizing the need for maintaining awareness of mass volumes of network state. SR satisfies essential requirements for application-enabled routing in software defined networks, including the ability to provide strict network performance guarantees, efficient use of network resources and very high scalability for application-based transactions. Segment Routing relies on a small number of extensions to IS-IS and OSPF and can operate with an MPLS or an IPv6 data plane and integrates with the rich multi-service capabilities of MPLS such as L3VPN, VPWS, VPLS, E-VPN, etc.

This week is the industry’s leading IPv6 event, the World IPv6 Congress in Paris, France. Cisco Fellow Mark Townsley delivered the keynote again, this time with a theme around the “Mobile Business Case for IPv6”. What’s exciting is that in the mere 18 months since the World IPv6 Launch we’re already seeing significant adoption of the larger scale address protocol. Mark in fact specifically cites how Verizon Wireless is already sending 30% of its traffic to search engine giant Google over IPv6. Other wireless operators are going straight to IPv6 for 4G and LTE deployments as well. Read More »
